Factor when divides the function the remainder is zero. The factorized form of the function f(x)=125x⁶-8 is (5x²-2)(25x⁴ + 10x²+4).
What is a factor?A factor of a function is a factor which when multiplied by another the result is the function itself.
We know that in order to factorize a function, we need to take the common terms out from the expression,
[tex]f(x)=125x^6-8[/tex]
The given function can be written as,
[tex]f(x)=125x^6-8\\\\f(x)=5^3x^6-2^3\\\\f(x)=(5x^2)^3-2^3[/tex]
Now, we will use the algebraic property to solve the function.
[tex]f(x)=(5x^2)^3-2^3\\\\f(x)=(5x^2-2)(25x^4+10x^2+2^2)\\\\f(x)=(5x^2-2)(25x^4+10x^2+4)[/tex]
Hence, the factorized form of the function f(x)=125x⁶-8 is (5x²-2)(25x⁴ + 10x²+4).

a room to be carpeted measures 16 feet in length and 12 feet in width the carpet costs 30 per square yard what is the total cost
A room area
Lenght × Width = 16 × 12
= 192 square feet
1 square yard = 9 square feet
so 1 square feet = 1/9 square yard
192 square feet = 192 × 1/9 square yard
= 64/3 square yard
Total cost
$30 × 64/3 = $640

A triangle has an area of 13.5 square miles and a height of 4.5 miles. What is the length
of the base?
Answer:
6 miles
Step-by-step explanation:
Area is :
[tex]A = \frac{1}{2} hb[/tex] OR [tex]A = \frac{hb}{2}[/tex]
So base is :
[tex]b = 2 \frac{A}{h}[/tex]
Substituting values given:
b = 2 × (13.5÷4.5)
b = 2×3
b=6
Answer:
the length of the base= 6miles
Step-by-step explanation:
Area of triangle =1/2 *Base*Hight
Now we sub the values in the formula:
13.5 = 1/2 * (length of the base) * 4.5
length of the base = (2 * 13.5)/4.5
length of the base = 6 miles

16. Convert 100 meters per hour to inches per
second. (1 meter = 3.3 feet, 1 ft = 12 in, 1
hour = 60 minutes, 1 minute = 60 seconds)
(1.1 inch per second)
Answer:
0.106
Step-by-step explanation:
100 meters= 382 feet (per hour)
60 minutes in an hour
60 seconds in a minute
382/60=6.34 inches per minute (rounded to nearest tenth)
1 minute = 6.34 inches
6.34 / 60 = 0.106 (rounded to nearest thousandth)

Step-by-step explanation:
The solution is in the attached file filatache
Answer:
A = 70
B = 110
C = 110
Step-by-step explanation:
A is opposite of the 70 degree angle, and vertical angles are equal, so it is also 70 degrees.
A straight line is 180 degrees, so 70 + B = 180, making B = 110 degrees.
Both of these rules apply for C, making it also 110 degrees.

Which of the following statements about variables is false? a. Mathematical operations can be performed on a variable. b. The variable will always be the letter x. c. A mathematical statement can include more than one variable. d. A variable is a letter used to represent an unknown quantity.
Answer:
b. The variable will always be the letter x (false)
Step-by-step explanation:
Variables can be any letter or symbol. The letter x is often used as a variable, but that is not the only choice. Many formulas, for example, make use of variables that have letters reminding you what they stand for.
For example, the formula ...
A = 1/2(b1 +b2)h
uses the variables A, b1, b2, and h to represent area, base-1, base-2, and height, respectively. The letter x is not used at all.
The graph shows a point at (4,1) and a line segment with endpoint at (2,2) and (6,2) This line segment will be dilated with the point of dilation at (4, 1) and a scale factor of 2. What is the 2-coordinate of
one of the endpoints of the dilated segment?
Dilation involves changing the size of a figure
The endpoints of the image are (0,3) and (8,3)
How to determine the coordinates of the imageThe coordinates of the pre-image are give as:
(2,2) and (6,2)
The scale factor is given as:
k = 2
The center of dilation is given as:
(a,b) = (4,1)
The coordinates of the image are then calculated as:
(x,y) = (k(x -a) + a, k(y -b) + b)
For (2,2), we have:
[tex](x,y) \to (2(2 -4) + 4, 2(2 - 1) + 1)[/tex]
[tex](x,y) \to (0, 3)[/tex]
For (6,2), we have:
[tex](x,y) \to (2(6 -4) + 4, 2(2 - 1) + 1)[/tex]
[tex](x,y) \to (8, 3)[/tex]
Hence, the endpoints of the image are (0,3) and (8,3)

Two similar triangles have a pair of corresponding sides of length 12 meters and 8 meters.
The larger triangle has a perimeter of 48 meters and an area of 180 square meters. Find the
perimeter and area of the smaller triangle.
Answer:
32 m, 80 m^2
Step-by-step explanation:
Ratio of their sides = 12 : 8 = 3 : 2
Ratio of their perimeter = 3 : 2
so 48 : perimeter of smaller triangle = 3 : 2
Perimeter of smaller triangle = 48 * 2 / 3 = 32 m
Ratio of their areas = 3^2 : 2^2 = 9 : 4
so 180 : area of smaller triangle = 9 : 4
Area of smaller triangle = 180 * 4 / 9 = 80 m^2

The Sugar Sweet Company is going to transport its sugar to market. It will cost $6500 to rent trucks plus $250 for each ton of sugar transported. The total cost, C (in dollars), for transporting n tons is given by the following.
c=6500+250n
1.If the total cost is $12,250, how many tons is the company transporting?
2.What is the total cost of transporting 14 tons?
Answer:
An equation that relates cost to the amount of sugar S C = 6500 + 250s the total cost is $1120 The total cost of transporting 19 tons of sugar at 250 each C = total cost C =6500 + 250(19) total cost = 6500 + 4750 = 11250

In an experiment to learn whether Substance M can help restore memory, the brains of 20 rats were treated to damage their memories. First, the rats were trained to run a maze. After a day, 10 rats (determined at random) were given M and 7 of them succeeded in the maze. Only 2 of the 10 control rats were successful. The two-sample z test for "no difference" against "a significantly higher proportion of the M group succeeds"
a) should not be used because the Large Counts condition is violated.
b) gives z = 2.25, P < 0.02
c) gives z = 2.60, P < 0.005
d) should not be used because the Random condition is violated
e) gives z = 2.25, P < 0.04 but not < 0.02
The number of rats in the sample are less than 30, therefore, according
to the central limit theorem, cannot approximate the population.
Response:
a) Should not be used because the Large Counts Condition is violated
Which condition are necessary for the hypothesis test?The proportion of the rats given M that succeeded, [tex]\hat p_1[/tex] = 7 ÷ 10 = 0.7
The proportion of the control rats that succeeded, [tex]\hat p_2[/tex] = 2 ÷ 10 = 0.2
H₀: [tex]\hat p_1[/tex] = [tex]\hat p_2[/tex]
Hₐ: [tex]\hat p_1[/tex] > [tex]\hat p_2[/tex]
The z-test formula for the difference between two proportion is given as follows;
[tex]Z= \mathbf{\dfrac{\hat{p}_1-\hat{p}_2}{\sqrt{\hat{p} \cdot (1-\hat{p})\left (\dfrac{1}{n_{1}}+\dfrac{1}{n_{2}} \right )}}}[/tex]
Where;
[tex]\hat p = \dfrac{7 + 2}{10 + 10} = 0.45[/tex]
[tex]Z=\dfrac{0.7-0.2}{\sqrt{0.45\times (1-0.45) \times \left (\dfrac{1}{10}+\dfrac{1}{10} \right )}} \approx \mathbf{ 2.25}[/tex]
p = 1 - p(z < 2.25) = 1 - 0.9878 = 0.0122
However, the number of rats in the sample, n are less than 30
Therefore;
The sample is not large enough for the test compared to the population,
and for a normal approximation which gives;
a) Should not be used because the Large Counts Condition is violated
